LASTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 488,998, dated January3, 1893.

Application filed August 25, 1888. Serial No. 283,704. (N model.)

the lasting jaws, whereby they may be read-g ily shifted laterallywithout necessarily vary-I ing their relation to each other,in order toadapt them for operation in connection with Heretofore it has beencustomary to adjust and fasten a right or a left last, as required.

the supports independently, a plan which involves considerable loss oftime, and much care in adjusting the parts. My invention is designed tomeet these points of objection to former machines.

In the accompanying drawings,-Figure l is a perspective View of so muchof a lasting.

machine as is necessary to illustrate the invention; Fig. 2 is a rearelevation of a lasting machine embodying my invention, and Figs. 3, 4,and 5, are vertical sectional views illustrating modifications.

A indicates the framework of a lasting machine, which may be of anyusual style and construction; B, O, the last supports; D, E, the lastingjaws and F, G, the supports which carry the jaw-shanks or racks,-theseparts being here represented in the forms used in the machine patentedto Paine, Gray, and 4 Pettee, August 7th 1888, No.387,366,in which Imore particularly contemplate using the present improvements. Themechanism for actuating the jaws, and other parts of the machine arefully described in said patent, to which reference may be made for suchparts as are not necessary to or involved in the present invention andtherefore not described herein.

H indicates a cross bar or rod connecting the two posts F, G, whichconnection may be either in front or in rear of the upright back plateof frame A. Figs. 1 and 2 show the connection in rear of said backplate,whi1e Figs. 3, 4 and 5 show it in front. When the rear connectionis used the blocks F G upon which the posts F, G, are carried, areconnected with the cross bar H by screws I, swiveled in ears or lugs,ct, at the ends of said cross bar, and screwing into the blocks I G, asindicated. The screws thus arranged, not only connect the blocks F, Gwith the cross bar, but they also afford means for independent andrelative adjustment of the blocks and posts, which is sometimesrequired. The

connected parts are moved across the back plate of frame A by anysuitable device, a lever J for this purpose being represented in Fig. 2.

i W hen it is desired to shift the side lasting jaws from one positionto the other;that is from the position proper for a right last to thatfor a left, or vice versa, it is only necessary to throw lever J in theproper direction. The lover or the cross bar may, if necessarv, belocked in its adjusted position, though this is not ordinarily required.

In Fig. 3 the cross bar II is represented as attached permanently toblock G and having an adjustable connection with block F through a tapbolt, b, passing through a slot c in the cross barand into the block.Asimilar bolt, d, passing through a slot 6 in a lug or earf of the blockF serves to hold the connected parts wherever adj ust-ed, whilepermitting them to be adjusted as a whole when required.

In Fig. 4 the connecting bar is represented as in the form of a rightand left screw, entering correspondingly-threaded holes or sockets inthe blocks F, G, and ahand lever J, is shown for moving the blocks thusconnected.

Fig. 5 shows the cross bar or connection in the form of a rod, swiveledin one of the blocks F "and screwing into the other,a screw being shownfor moving the connected blocks.

Under each and all of these modifications, either block may be adjustedindependently of the other, and both may be moved simultaneously andequally.

Various other modifications, the mechanical equivalents of the foregoingwill readily suggest themselves to the mechanic. It is also apparentthat instead of the lever or the screw shown for moving the connectedpostblocks, a cam, Wedge, or other well known equivalent may be employedas a shiftingdevice.

It is to be observed that under the construction above set forth, thesupports in which are carried the jaw-shanks or racks, are so connectedthat they may be moved in unison or as though they were one integralbody,in which case they maintain a given relation one to the other, butare varied as to their relation to the intermediate last support. Itwill likewise beseen that the adjustability of the connection betweenthe said jaw-supports, permits the distance between them to be varied,and thereby enables the operator to adjust the machine to lasts ofvarying width,-the'play of the jaws remaining the same in extent, butthestarting and stopping points being changedby change in adjustment oftheir supporting posts.

The term jaw is used throughout in the sense in which it is commonlyused in connection with this class of machines, and means the stock,body, or head which carries the blades, wipers, or fingers, and does notmean the blades or fingers themselves.

The invention is to be readily distinguished from that class of lastingmachines in which, by the use of cords and pulleys, equalizers, andshifting driving gear the separate lasting blades or fingers of eachjaw, and the jaws at the opposite sides of the last are enabled to movevariable distances, determined by the contour of the last or any otherobstacle with which they may chance to come into contact. The movementsof the jaws under any given adjustment, are uniform and certain under myconstruction.

Having thus described my invention what I claim is,

1. In a lasting machine, the combination with a last-support, of jaw-supports connected with each other and adapted to be movedsimultaneously and equally toward and from the last-supports, andlasting jaws movable upon and relatively to their supports.

2. In a lasting machine, the combination with a last-support, oflasting-jaw-supports connected one with the other, a shifting deviceconnected with one of the jaw-supports and serving to move the sametoward and from the last-support, and lasting-jaws movable relatively totheir supports.

3. In a lasting machine, the combination with a last-support, of movablelasting-jawsupports, an adjustable connecting bar extending from onesupport to the other, and lasting-jaws movable relatively to theirsupports all substantially as shown, whereby the jaw-supports may bemoved in unison or adjusted independently toward or from thelastsupports as desired.

4. In a lasting machine, the combination with a last-support, oflasting-jaw-supports capable of independent adjustment towardv and fromthe last-supports, a connecting bar extending from one jaw-support tothe other, a shifting device adapted to move the connected supports, andlasting-jaws movable relatively to their supports.

5. In combination with the frame of alast ing machine, a last support,side lasting jaws D, E, supports F F and G G for said jaws, connectingbar H extending from one support to the other, and lever J connectedwith and serving to move the parts, substantially as set forth.

6. In a lasting machine the combination of a last, lasting-jaw-supportscapable of adj ustment toward and from the last, and lastingjaws movablein and relatively to the supports. substantially as set forth.

In witness whereof I hereunto set my hand in the presence of twowitnesses.
